Good point, should not use chunked if not HTTP/1.1
i will take a look

Is there a way to disable using chunked encoding to reply to a
particular request?
AFAICT (with enabletclpages on), any *.tcl page under the documentroot will
have its content returned to the user with a Transfer-Encoding: chunked,
regardless of whether the request is HTTP/0.9, HTTP/1.0 or HTTP/1.1.
For modern browsers this isn't an issue as they'll generally always make
(and understand a response in) HTTP/1.1 requests. But for some clients
(i.e., Lynx, wget, etc.) that don't expect an HTTP/1.1 encoded reply the
transfer-encoding byte ranges end up being interpreted as part of the
response body.
For example, I have the following one line script in
$NSHOME/pages/hello.tcl:
ns_return 200 text/plain "Hello World"
## HTTP/1.1 request (expected result)
[EMAIL PROTECTED]:/usr/local/ns/pages$ telnet localhost 80
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
GET /hello.tcl HTTP/1.1
Host: localhost
Connection: close
HTTP/1.1 200 OK
MIME-Version: 1.0
Accept-Ranges: bytes
Date: Mon, 19 Feb 2007 19:06:01 GMT
Server: NaviServer/4.99.2
Content-Type: text/plain; charset=utf-8
Transfer-Encoding: chunked
Connection: close
b
Hello World
0

## HTTP/1.0 request (unexpected result)
[EMAIL PROTECTED]:/usr/local/ns/pages$ telnet localhost 80
Trying 127.0.0.1...

Escape character is '^]'.
GET /hello.tcl HTTP/1.0
Connection: close
HTTP/1.1 200 OK
MIME-Version: 1.0

Date: Mon, 19 Feb 2007 19:06:14 GMT
Server: NaviServer/4.99.2
Content-Type: text/plain; charset=utf-8

b

## HTTP/0.9 request (unexpected result; do we need
## to even support HTTP/0.9 really?)
[EMAIL PROTECTED]:/usr/local/ns/pages$ telnet localhost 80
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
GET /hello.tcl
b
Hello World

## From Lynx (unexpected result)
[EMAIL PROTECTED]:/usr/local/ns/pages$ lynx -dump http://localhost/hello.tcl
b
Hello World

(All of the above tested with Naviserver compiled from CVS HEAD as of Feb
7th, 2007 & Tcl 8.4.14 under Debian.)
Thanks,
